Serial Number 6524487 was reported as inaccurate.

Note: My watch is this movement, but it is in full
hunter case with cuvette. The case is by the
Philidelphia Watch Company and is numbered 7285639
with twenty year guarantee.
Based up the full hunter case cited and
cuvette, I believe that the valuation cited is too
low and incorrect, please correct when convenient
and thank you for an excellent resource.
